What is a wavelength service?

A wavelength service gives you a dedicated optical channel — a single "color" of light — across our fiber backbone using Dense Wavelength-Division Multiplexing (DWDM). It delivers a private, high-capacity transport circuit from 100 Mbps up to 400/800 Gbps that behaves like your own fiber, without the cost and complexity of lighting an entire strand yourself. For organizations moving enormous amounts of data over distance, a wavelength is the most efficient path to massive, predictable bandwidth.

How DWDM optical transport works

DWDM lets many independent wavelengths travel down a single fiber simultaneously, each on its own discrete color of light. Your wavelength is optically isolated from every other channel, so it carries your traffic at full, uncontended capacity while sharing the same physical glass. This is how carriers and hyperscalers pack terabits of capacity onto existing routes — and it's the engine behind every Vast Networks wavelength service.

Protocol transparent by design

A wavelength carries your traffic exactly as you frame it. Run Ethernet, OTN, or Fibre Channel and the wave transports it untouched — your equipment, your framing, your control. That transparency makes wavelength services the natural fit for data center interconnect, SAN extension, and storage replication that expect native protocols from end to end with no translation in between.

Built for metro and long-haul distance

Wavelength services are engineered for reach. Using amplified optical paths across our DWDM core, we deliver dedicated waves across metro and long-haul distances with ultra-low latency, and we design the route around the performance your application demands. Optional protected or diverse routing adds resilience for the circuits your business can't afford to lose.

When to choose a wavelength

If a single circuit needs to move huge volumes of data between two points — data center to data center, backbone node to backbone node, or cloud on-ramp — a wavelength service is usually the answer. It's the choice for carrier and service-provider backbones, large-scale disaster-recovery replication, research, media, and HPC networks, and any workload that has simply outgrown lit fiber. Every wave is backed by a carrier-grade uptime SLA and monitored 24/7 by our California-based NOC.

Wavelength services FAQs

Common questions about wavelength services, DWDM, protocol transparency, and reach.

What is a wavelength service?

A wavelength service delivers a dedicated optical channel — a single "color" of light — across a shared fiber using Dense Wavelength-Division Multiplexing (DWDM). You get a private, high-capacity transport circuit from 100 Mbps up to 400/800 Gbps that behaves like your own fiber, without the cost of lighting an entire strand yourself.

What does DWDM mean?

DWDM, or Dense Wavelength-Division Multiplexing, is the optical technology that lets many independent wavelengths travel down a single fiber at the same time. Each wavelength is isolated, so your channel carries your traffic at full capacity while other waves share the same physical glass — an extremely efficient way to scale long-haul transport.

What does "protocol transparent" mean?

A wavelength carries your traffic exactly as you frame it. Whether you run Ethernet, OTN, or Fibre Channel, the wave transports it untouched — your equipment, your framing, your control. That transparency makes wavelength services ideal for data center interconnect and storage replication that expect native protocols end-to-end.

How is wavelength different from dedicated internet or point-to-point?

Dedicated internet access provides managed connectivity to the public internet. Point-to-point provides private Layer 2 links between sites. Wavelength services provide raw, high-capacity optical transport — typically point-to-point between data centers or backbone nodes — for workloads that need massive, protocol-transparent bandwidth over distance.

How far can a wavelength service reach?

Wavelengths are engineered for both metro and long-haul distances using amplified optical paths over our DWDM backbone. We design the route for the reach and latency your application requires, with optional protected or diverse routing for resilience.

Who uses wavelength services?

Wavelength services are built for the most demanding transport needs: data center to data center connectivity, carrier and service-provider backbones, large-scale storage and disaster-recovery replication, research, media, and HPC networks, and cloud on-ramps. If a single circuit needs to move enormous amounts of data over distance, a wavelength is usually the answer.
